I don't have exact numbers but if say 50% of what I have is tins and around 25% each split between mason jars and mylar. If I could do it over, there would be no mason jars for bulk, all mylar. I don't understand the vacuum seal concept, oxygen is required for aerobic aging. You're not preserving good, you're storing and aging tobacco.
I also figured out mason jars suck for flake unless you leave it really loose.
If you're going to cellar 25 pounds or so, I'd go mostly with tins. The savings with bulk for that amount is mostly negligible.
